Hi,
I'm using Mesa (specifically Gallium on LLVMPipe) to run an old game
called Star Trek Voyager Elite Force.
I'd like to report a bug introduced with version 18.0.0 and still
present in Mesa master that completely breaks the shadows in this game.
I don't know how Mesa works internally so I'll just attach 2 videos:
* Mesa 17.3.7: shadows work normally:

* Mesa 18.0.0 and newer: shadows are broken:

The game uses the id3 engine so I assume other games are also affected,
although I haven't tested it.
For what it's worth, the proprietary AMD drivers have the same bug.
If you need the game for testing, please let me know.
A demo is also available here:
